NUT-LOCK.

Specification of Letters Patent.

Patented lvlay 7,1907.

Application filed March 5, 1907. Serial No. 860,637.

T0 at whom it may concern:

Be it known that I, AUGUST ANDERSON, a citizen of the United States, residing at Birmingham, in the .county of Jefferson and State of Alabama, have invented new and useful Improvements in Nut-Locks, of which the following is a specification.

My invention pertains to nut locks, and seeks to provide an inexpensive, practical and easily applied construction for looking a plurality of nuts employed in a railway rail joint or other connection.

With the foregoing in mind the invention will be fully understood from the following description and claims when the same are read in connection with the accompanying drawings, forming part of this specification, in which:

Figure 1 is a side elevation of a railway rail joint equipped with my improvements. Fig. 2 is an enlarged transverse section taken in the plane of the line 2 2 of Fig. 1. Fig. 3 is a detail perspective view illustrative of the hinged locking plate and the bracket to which the same is connected, and: Fig. 4 is a view of a modified nut-engaging bar hereinafter referred to in detail.

Referring by letter to the said drawings, and more particularly to Figs. 1 to 3 thereof:

A A are the meeting portions of two railway rails.

B B are fish-plates arranged at opposite sides of the webs of the rails and interposed between the bases and heads thereof in the ordinary manner.

0 O are bolts extending through the rail webs and the fish-plates and equipped with nuts D, and E is the nut-engaging bar of my improvements. The said nut-engaging bar E may be of steel or any other material consonant with the purpose of the invention and may be engaged with the nuts D in any approved manner without involving departure from the scope of my invention as claimed. I prefer, however, to provide the said bar with a plurality of apertures F of a shape and size to freely receive the nuts D.

In addition to the nut-engaging bar E, my novel nut lock comprises a bolt G extending loosely through the said bar and turned into threaded engagement with the adjacent fishplate B and having an angular head g, a hinged plate H of steel or other material, and a cotter pin I. The hinged plate H is bifurcated at h to receive the angular head 9 of the bolt G, and is connected through a bolt J which extends through an eye h at its upper end with ears 7c depending from a bracket K which latter is disposed laterally with respect to the bar E. The said bracket K maybe fixed to the bar E in any manner compatible with the purpose of my invention, though I prefer to arrange the bracket directly on the upper edge of the bar and to connect the former to the latter through the medium of threaded bolts 1 extending through the llgracket and into threaded apertures in the The nut-engaging bar E shown in Fig. 4E differs from the bar E in that it has notches F instead of rectangular openings to receive the nuts D, but it will be readily apparent that the bar E is equally as efficient as the bar E in performing the function ascribed. to the nut-engaging bar.

In assembling the parts of my improvements, the rails, fish-plates, bolts and nuts are arranged in the manner common in railway construction, and the nut-engaging bar is positioned between the bases and heads of the rails and so that it receives the nuts D after the manner illustrated. The bolt G is then turned through the nut-engaging bar and into engagement with the threaded socket in the adjacent fish-plate, and when the bolt is turned home, the plate II is swung downward so as to receive in its bifurcation the angular head of the bolt G and in that way preclude casual turning of the bolt. The cotter pin I is then secured in an aperture in the head of the bolt G and at the outer side of the plate II; the said pin having for its office to hold the plate IiI against swinging out of engagement with the head of the bolt. With the parts arranged as shown, it will be apparent that the bolt G retains the bar E in proper position relative to the nuts, and that the said bar is calculated in turn to effectually prevent casual loosening or turning of all of the nuts which it engages and in that way contribute to the strengthand'safety of the rail joint or other connection in which it is employed.

l/Vhen it is desired for any reason to remove any one or all of the nuts D from their complementary bolts, the same may be accomplished after the bar E isremoved, and such removal may be effected by removing the cotter pin I, swinging the plate II up out of engagement with the head of the boltG,

IIO

turning said bolt G out of engagement with the adjacent fish-plate, and taking the bar E off of the nuts D.

It will be gathered from the foregoing that my improvements may be expeditiously and easily placed and secured in position to lock a plurality of nuts, and may be as readily removed when it is desired to release the nuts, and this latter notwithstanding the fact that there is no liability of the nuts being casually released while the nut lock is in use. It will also be gathered that in addition to securely fixing the nuts D against casual turning, my improvements are calculated to increase the strength of a rail joint or analogous connection as a whole.

The construction herein shown and de scribed is the preferred embodiment of my invention, but it is obvious that in practice such changes or modifications may be made as fairly fall within the scope of my invention as defined in the claims appended.

Having described my invention, what I claim and desireto secure by Letters-Patent, is:

1. In a nut lock, the combination of a fishplate, a plurality of bolts extending therethrough, nuts mounted on the bolts, a bar engaging the nuts to hold the same against rotation, a bolt extending through the nutengaging bar and turned into threaded engagement with the fish-plate and having an angular head in which is an aperture, a plate connected in a hinged manner with the nutengaging bar and bifurcated to receive the angular head of the bolt, and a cotter pin extendingthrough the aperture in the angular head of the bolt and arranged at the outer side of the said plate.

2. In a nut lock, the combination of a fishplate, a plurality of bolts extending therethrough, nuts mounted on the bolts, a bar engaging the nuts to hold the same against rotation, a bolt extending through the nut-engaging bar and turned into threaded engagement with the fish-plate and having an angular head in which is an aperture, a bracket fixed to and extending laterally from the nutengaging bar and having ears at its ends in which are apertures, a bolt extending through said apertures and carried by said ears, a plate havingan eye receiving the last mentioned bolt and also having a bifurcation to receive the angular head .of the second mentioned bolt, and a cotter pin extending through the aperture in said head and arranged at the outer side of said plate.

3. A device for the purpose described, com prising a nut-engaging bar, a bolt arranged to turn in the bar and connect the same to another element and having an angular head and also having an aperture in said head, a

plate hinged to the nut-engaging bar and bifurcated to receive the head of the bolt, and a cotter pin extending through the aperture in the bolt-head and arranged at the outer side of the hinged plate.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
